Wireless printing saves time and eliminates cable clutter, but connecting a printer HP DeskJet 3639 Wi-Fi is often a source of concern. This model supports several network connection methods, from standard WPS to manually entering settings through the control panel. In this article, we'll cover all the current methods, including nuances for different firmware versions and common errors that prevent setup.

Peculiarity DeskJet 3639 — the lack of a display, which complicates the process for beginners. However, the manufacturer has provided alternative options: connecting via a USB cable for initial setup or using a mobile app. HP SmartWe tested all the methods in practice and selected the most reliable one—one with the lowest risk of failure.

If your router supports WPS (Wi-Fi Protected Setup), setup will take no more than 2 minutes. Otherwise, you'll have to manually enter the network name and password—the key here is to be careful with the case. We'll also reveal secret printer diagnostic mode, which helps determine the cause of the problem without contacting a service center.

1. Preparing for connection: what to check before starting setup

Before you start connecting HP DeskJet 3639 with Wi-Fi, make sure the basic conditions are met. Missing even one item from this list can lead to errors like "Failed to connect to the network" or "Printer not found».

• 📶 The router is turned on and distributing Wi-Fi.Check that the wireless network indicator on your router is green or blue (depending on the model). If it's blinking orange, reboot the router.
• 🔌 The printer is connected to a 220V network.Make sure the power cord is firmly inserted into the wall outlet and the connector on the back panel. DeskJet 3639The power indicator should be on continuously, without blinking.
• 📱 Do you have the connection data?. Prepare the network name in advance (SSID) and password. If you don't remember it, look at the sticker on the back of the router or in the web interface (usually 192.168.0.1 or 192.168.1.1).
• 🖨️ The printer is in factory conditionIf you have previously tried to connect it to a different network, perform a reset (hold down the button Wi-Fi And Cancel for 10 seconds).
